INDUCTIVELY COUPLED PLASMA-MASS SPECTROSCOPY (ICP-MS)

Description

ICP-MS is a technique based on the ionization of atoms by means of sustained argon plasma. Positive ions are accelerated into the mass separation device to be separated by mass/charge in the quadrupole or by mass and momentum in the Electrostatic Analyzer (ESA).

Due to extensive instrumental setup protocols, a four-hour minimum charge is required for ICP-MS use. No-shows will be charged for four hours unless they contact Waleska Castro to cancel at least twelve hours in advance
No charge for tune-up and calibration procedures (~1 hour)
Users will be charged regular rates for training to run the ICP-MS. However, they will be credited those charges when they run their own samples.

Technique Advantages

Rapid multi-elemental analysis capability, covering most of the elements in the Periodic Table.
Variable mass resolution of 300, 4000 and 10,000, and hence, capable of achieving unambiguous and accurate elemental analysis through identification and removal of interference at high resolution.
Polyatomic and isotope interferences can be avoided to accurately determine the analyte element..
Ultra-high sensitivity and low dark noise, resulting in excellent detection limits at the pg/L and ng/L levels.
Linear response over more than 9 orders of magnitude and simultaneous analog and digital signal registration
Precise and accurate isotope ratio measurements for some isotopic systems.
Accurate and sensitive detection of transient signals for speciation analysis.

Typical Applications

Trace elements in a wide variety of aqueous matrices: drinking water, river, lake and ground water, waste water and effluent, and seawater.
Trace elements in solids after digestion: sediment, soil, sludge, road dust, air particulate matter, plant tissue and grain, rocks and minerals, etc.
Trace elements in samples of body fluids, including blood, plasma, and urine.
